+# resolve
+
+implements the [node `require.resolve()`
+algorithm](https://nodejs.org/api/modules.html#modules_all_together)
+such that you can `require.resolve()` on behalf of a file asynchronously and
+synchronously
+
+[![build status](https://secure.travis-ci.org/browserify/node-resolve.png)](http://travis-ci.org/browserify/node-resolve)
+
+# example
+
+asynchronously resolve:
+
+```js
+var resolve = require('resolve');
+resolve('tap', { basedir: __dirname }, function (err, res) {
+    if (err) console.error(err);
+    else console.log(res);
+});
+```
+
+```
+$ node example/async.js
+/home/substack/projects/node-resolve/node_modules/tap/lib/main.js
+```
+
+synchronously resolve:
+
+```js
+var resolve = require('resolve');
+var res = resolve.sync('tap', { basedir: __dirname });
+console.log(res);
+```
+
+```
+$ node example/sync.js
+/home/substack/projects/node-resolve/node_modules/tap/lib/main.js
+```
+
+# methods
+
+```js
+var resolve = require('resolve');
+```
+
+## resolve(id, opts={}, cb)
+
+Asynchronously resolve the module path string `id` into `cb(err, res [, pkg])`, where `pkg` (if defined) is the data from `package.json`.
+
+options are:
+
+* opts.basedir - directory to begin resolving from
+
+* opts.package - `package.json` data applicable to the module being loaded
+
+* opts.extensions - array of file extensions to search in order
+
+* opts.readFile - how to read files asynchronously
+
+* opts.isFile - function to asynchronously test whether a file exists
+
+* `opts.packageFilter(pkg, pkgfile)` - transform the parsed package.json contents before looking at the "main" field
+  * pkg - package data
+  * pkgfile - path to package.json
+
+* `opts.pathFilter(pkg, path, relativePath)` - transform a path within a package
+  * pkg - package data
+  * path - the path being resolved
+  * relativePath - the path relative from the package.json location
+  * returns - a relative path that will be joined from the package.json location
+
+* opts.paths - require.paths array to use if nothing is found on the normal `node_modules` recursive walk (probably don't use this)
+
+* opts.moduleDirectory - directory (or directories) in which to recursively look for modules. default: `"node_modules"`
+
+* opts.preserveSymlinks - if true, doesn't resolve `basedir` to real path before resolving.
+This is the way Node resolves dependencies when executed with the [--preserve-symlinks](https://nodejs.org/api/all.html#cli_preserve_symlinks) flag.
+**Note:** this property is currently `true` by default but it will be changed to
+`false` in the next major version because *Node's resolution algorithm does not preserve symlinks by default*.
+
+default `opts` values:
+
+```js
+{
+    paths: [],
+    basedir: __dirname,
+    extensions: ['.js'],
+    readFile: fs.readFile,
+    isFile: function isFile(file, cb) {
+        fs.stat(file, function (err, stat) {
+            if (!err) {
+                return cb(null, stat.isFile() || stat.isFIFO());
+            }
+            if (err.code === 'ENOENT' || err.code === 'ENOTDIR') return cb(null, false);
+            return cb(err);
+        });
+    },
+    moduleDirectory: 'node_modules',
+    preserveSymlinks: true
+}
+```
+
+## resolve.sync(id, opts)
+
+Synchronously resolve the module path string `id`, returning the result and
+throwing an error when `id` can't be resolved.
+
+options are:
+
+* opts.basedir - directory to begin resolving from
+
+* opts.extensions - array of file extensions to search in order
+
+* opts.readFile - how to read files synchronously
+
+* opts.isFile - function to synchronously test whether a file exists
+
+* `opts.packageFilter(pkg, dir)` - transform the parsed package.json contents before looking at the "main" field
+  * pkg - package data
+  * dir - directory for package.json (Note: the second argument will change to "pkgfile" in v2)
+
+* `opts.pathFilter(pkg, path, relativePath)` - transform a path within a package
+  * pkg - package data
+  * path - the path being resolved
+  * relativePath - the path relative from the package.json location
+  * returns - a relative path that will be joined from the package.json location
+
+* opts.paths - require.paths array to use if nothing is found on the normal `node_modules` recursive walk (probably don't use this)
+
+* opts.moduleDirectory - directory (or directories) in which to recursively look for modules. default: `"node_modules"`
+
+* opts.preserveSymlinks - if true, doesn't resolve `basedir` to real path before resolving.
+This is the way Node resolves dependencies when executed with the [--preserve-symlinks](https://nodejs.org/api/all.html#cli_preserve_symlinks) flag.
+**Note:** this property is currently `true` by default but it will be changed to
+`false` in the next major version because *Node's resolution algorithm does not preserve symlinks by default*.
+
+default `opts` values:

+        } catch (e) {

+        return stat.isFile() || stat.isFIFO();
+    },

+```
+
+## resolve.isCore(pkg)
